Drying of immobilized yeast cells in a spouted bed dryer with a moving draft tube / Sušenje imobilisanih ćelija pivskog kvasca u sušioniku sa fontanskim slojem i pokretnom centralnom cevi
(Association of the Chemical Engineers of Serbia, 2010)
Brewery yeast cells immobilized in Ca-alginate were dried in a laboratory scale spouted bed with a draft tube. The experiment was conducted under variable temperatures and air flow rates. The temperature and air velocity ...
Diffusion of lidocaine hydrochloride from lipid microparticles
(Association of the Chemical Engineers of Serbia, 2009)
Lipid particles, as drug carriers, are of increasing research interest, because a sustained drug release and avoidance of side effects could be achieved by using them. Lidocaine hydrochloride is a very efficient local ...
EI/MS/MS spectra of N-monosubstituted cyanoacetamides / EI/MS/MS spektri N-monosupstituisanih cijanoacetamida
(Association of the Chemical Engineers of Serbia, 2010)
The electron-ionization induced mass spectra of twenty six N-monosubstituted cyanoacetamides were recorded and their fragmentation patterns were studied. The effect of N-alkyl and N-aryl substituents to the fragmentation ...
A study of the photocatalytic degradation of methomyl by UV light
(Association of the Chemical Engineers of Serbia, 2009)
The photocatalytic degradation of insecticide methomyl in water, using TiO2 and ZnO (Merck), under UV (366 nm) was studied. The influence of the catalyst concentration and pH was investigated. The optimal concentration of ...
Effects of cell addition on immobilization by electrostatic droplet generation / Uticaj prisustva ćelija u procesu elektrostatičke ekstruzije alginata
(Association of the Chemical Engineers of Serbia, 2005)
In this study, an attempt was made to assess the effects of cell addition and final concentration on the process of electrostatic extrusion as a method for cell immobilization in alginate microbeads. The electrostatic ...
Energy saving in the supercritical carbon dioxide extraction of essential oils from species of the Lamiaceae family / Ušteda energije u procesima ekstrakcije etarskih ulja biljaka familije Lamiaceae natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2006)
The reduction of energy consumption in the supercritical carbon dioxide extraction of essential oils from leaves of species of the Lamiaceae family due to the optimal pretreatment of herbaceous material was studied in the ...
Hydrodesulfurization of light gas oil - kinetic determination in a batch reactor / Hidrodesulfurizacija lakog gasnog ulja - ispitivanje kinetike HDS u šaržnom reaktoru
(Association of the Chemical Engineers of Serbia, 2002)
The performed investigations were directed toward the analysis of the performance and activity of the fresh and regenerated Cyanamid HDS 20C catalyst in a laboratory batch reactor (2 dm3) for the HDS of the diesel fraction ...
Nanocomposite powders for new contact materials based on copper and alumina
(Association of the Chemical Engineers of Serbia, 2008)
This paper is a contribution to characterization of Cu-Al2O3 powders with nanostructure designed for the production of dispersion strengthened contact materials. New materials with predetermined properties can be successfully ...
Design and optimization of purification procedure for biodiesel washing
(Association of the Chemical Engineers of Serbia, 2009)
Almost complete methanolysis of triglycerides is usually not enough to fulfil the strict standards of biodiesel quality. A key step in this process is neutralization of alkali (catalyst) followed by the washing procedure ...
The optimization of zinc dialkyldithiocarbamates synthesis and determination of their antioxidant activity
(Association of the Chemical Engineers of Serbia, 2008)
A two-step optimized laboratory synthetic method of zinc dialkyldithiocarbamates is presented. In the course of the first phase, a sodium salt of dialkyldithiocarbamic acid has been synthesized from the dialkylamines, ...
